Global Cities Covenant on Climate - The Mexico City Pact

The Mexico City Pact

The Global Cities Covenant on Climate - "The Mexico City Pact" is a voluntary initiative of mayors and local authority representatives that aims to advance climate actions. By signing the Pact, signatories commit to 10 action points, including the reduction of emissions, adaptation to the impacts of climate change and fostering city-to-city cooperation.

"Mayors and urban leaders are on the frontline of the planet's fight against a changing climate. The world's cities must join together and put their data in the same pot."

Marcelo Ebrard, Mayor of Mexico City and Chair of the World Mayors Council on Climate Change

The Mexico City Pact builds on existing regional action (e.g. Covenant of Mayors in Europe or the US Conference of Mayors Climate Protection Agreement) and the achievements of global advocacy through Local Government Climate Roadmap. The Mexico City Pact goes even further through the introduction of the concept of globally measurable, reportable, and verifiable (MRV) local climate action.

"The Mexico City Pact sends a key signal to the negotiations that it can indeed be done, and that millions, if not billions, of people around the world are ready to begin implementing climate change action."

Christiana Figueres, UNFCCC Executive Secretary

carbonn Cities Climate Registry (cCCR)

The carbonn Climate Registry (cCR)* is a global mechanism for cities and local government to make commitments to climate change that the world can count on.

Article.4 of the Mexico City Pact envisages that signatories report their climate commitments, performance and actions through the carbonn Cities Climate Registry.

Developed by local governments for local governments, the cCR supports the global credibility of local climate action by ensuring transparency, accountability and comparability and presents the global response of local governments to measurable, reportable, verifiable climate action.

The cCR is operated by the Bonn Center for Local Climate Action and Reporting - carbonn.
